Quickboost provides Su-9 air scoops consisting of eight parts. Of note is the re-sealable packaging that Quickboost uses making the parts easy to review and then stuff securely back into the package. The supplied instructions address the replacement of the corresponding Trumpeter parts.
Quickboost has molded the air scoops perfectly in tan resin with no apparent bubbles. The Quickboost air scoops provide no mold seams to sand off on these tiny parts along with the superior detail.
Although most paints will adhere to resin alone, I would recommend that you wash the parts to remove any remaining mold release and prime them first. They will need to be installed with your favorite CA (super glue) or epoxy, as the normal plastic glues or solvents will not react with the resin.
